TELEGRAPH msmmsm.

Be it known-that I, EARL L. GI LEILAND;

a citizen'oi the' United States, residing at Grand 'Forks, in the county of Grand Forks and State of NorthDakota, invented certain new and useful I1nprovemerits in Telegraph Instruments; and I do declare the following to be 'a'vfull, clear, and

eXact descrip'tion of the. invention, suchas will enable others skilled in the art to which it appertains to-make and use the same.

Tliis' ii1vention relates to telegraphi i fi nt's ut more especially to those ut lizedfor receiving 'pi1rposes.

'1 invention is to proone obj eet of Jactefspee'i'fied through the instrumeumuty; of" which the. necessity for the usual local cireuitfand aceompanymg sounder therein is'ellininated. I

Another and further object of the invention is "to .providea single instrument having 'a' combined relay and sounder so assodated as' to. be operated simultaneously;

rAn'other and stillj'further object resides in providing a combined relay and sounder having ineansflby which the sounder if desirable may be eliminated, and the relay used to control a therein as is now customary.

' jAnother andfurther ob .ect'-1sto"provide a novel retractilemeans for the stop of the sounder/as well'as the armature ofthe re and a'finalobjectis to produce a'sim- 1a}? ple, easily constructed efiicie'nt and inexpenoperae as clearly and distinctly-as it would if included in a usual local circuit.

myiinv'ention consists of certain novel features, of construction, combination and, ar-

rangement of parts to be more particularly hereinafterset forth and claimed.

In the accompanying drawings in which corresponding parts are indicated by simi lar reference. characters Figure 1 is a, side elevation of my; improved relay and sounder Fig. 2 is a top plan View thereof:

sult'thearmatureof the relay is very light and thin so that consequently its clicks are almost indistinguishable. 'Therefore it is necessary in order to clearly bring out the signal being conveyed to provide the above referred tolocal circuit and sounder. This local circuit and sounder, however, in many 1 70 thatnew batteries" must be provided oe-i cas onally" further when the set is'i'n'iinstances has roved disadvantageous 1n tially installed an extra instrument is neces my, town: a s under. Now it is to overcome the necessity for this additional sounder and circuit that I propose to provide a single instrument constituting a com bined relay and sounder, the usual electromagnets of the latter however, being omit- V ted, which relay and sounder are so-connected ine'cha'nicallyas to operate, simulta- 'neously.

7 Further I propose to have the stop of the sounder connected to the armature of the relay in such a' manner that'when the latter is; actuated the stop will be broughtinto contact with its anvil so as to produce the L'various signals as clearly and distinctly asfthey would be produced if an ord'narv sounder was employed.

In carrying out the foregoing I provide a pedestal 1 surface of the pedestal 1 is disposed an insulating base 2'which carries the various parts constituting therelay under considera; tion. Two screws?) pass'through the base 2 at one end thereof and in spaced relation and are provided with threaded caps 4 forming binding posts to which are connected the leads from the main line. Two other screws 5 alsopass through the base 2 at one corresponds to that, of the two electr magnets 9 which are slidably mounted in said openings. The frame 7 is provided formed .of' metal, soap-stone or other suitableinaterial and uponthe upper with suitable legs which are s'ecured is i the upper surface; of the-base 2; as clearly shown .in Figs. 1, 2 and 4.. To the rear of the two electro-niagnets 9 whichvin this in .i

stance are the usual 150 ohm relay magnets isa standardll having a' transverse: thread-V.

ed opening through the upper end thereof.

An adjusting screw 121' has its threaded t I ,17 whioh latter.cooperates'witlitherespec tivecorges of electro-magnets 9o-as clearly Zea shank l3 passedthrough the' threaded openingin thestandard 10 and "engaged with a transverse bar 14, which connects therear of-the two electro-magnets 9; By; thisstruture it will be seen thatvwhen thea'djiisting screw. 12 is revolved the electro magnetsimay be'moved in and out of the QpeningsS-inthe frame 7 as desired.v

Immediately in front of the frame 7 upon -.the base 2 is Inountedaplate 2l whichlcarries a vertically, disposed yoke 22' rising from one end thereof; Also upon plate 21 forward of yoke 22 is an anvil 23 having the," usual set screw 24 the purpose of which: .will be hereinafter set forth.
